GMC Jimmy 1982-1995: A Guide to Universal Joint Replacement
Hearing clunks or feeling vibrations in your GMC Jimmy? It might be time for new U-joints.
- Listen for clunks when shifting, squeaks while driving, or new vibrations; these are the most common signs of a failing U-joint.
- For durability, especially on 4WD models, premium aftermarket brands like Dana/Spicer or Moog are highly recommended by other truck owners.
- If doing the job yourself, be sure to mark the driveshaft's position before removal to ensure it's reinstalled in balance.
- Do not ignore the symptoms. A complete U-joint failure can cause the driveshaft to detach, leaving you stranded and causing expensive damage.
Is Your GMC Jimmy's U-Joint Failing?
Universal joints are tough, but they do wear out. On a vehicle like the '82-'95 Jimmy, which has seen many years of service, U-joint failure is a common issue. Being aware of the symptoms can help you catch the problem before it leaves you stranded.
The most common signs are noises and vibrations. You might hear a loud "clunk" when you shift from Drive to Reverse. Another classic symptom is a rhythmic squeaking or chirping noise that gets faster as you speed up, which often points to a dry, unlubricated joint. As the wear gets worse, you may feel a vibration throughout the truck, especially at highway speeds. This can sometimes be mistaken for a tire issue, but if balancing your tires doesn't fix it, the U-joints are a likely suspect.
🎬 Watch: How to tell if your U-joint is badChoosing the Right Aftermarket U-Joint
For a vehicle from this era, you don't need to hunt for an original OEM part. High-quality aftermarket U-joints are widely available and often offer better features, such as grease fittings for easier maintenance. Aftermarket brands provide a range of options to fit your budget and how you use your Jimmy.
Greaseable vs. Sealed U-Joints
Many aftermarket U-joints are "greaseable," meaning they have a small fitting (a zerk fitting) that lets you add fresh grease. This can extend their life if you perform regular maintenance. Original factory joints were often "sealed" and non-greaseable. If you do a lot of off-roading or drive in wet conditions, greaseable joints are a great choice. For a daily driver, a high-quality sealed joint from a top brand is also an excellent, maintenance-free option.
Brand Quality Tiers
- Premium Brands (Dana/Spicer, Moog, SKF): These are the top choices for durability and performance. Dana/Spicer is often considered the gold standard, and many enthusiasts and mechanics prefer them for their strength, especially for off-road and heavy-use applications. Moog is another highly-regarded brand known for its "Super Strength" line and problem-solving designs that make installation easier. SKF is a major player in bearings and driveline parts, with their "Brute Force" line being a popular premium option.
- Standard Brands (GMB): GMB is a well-known manufacturer that provides reliable, budget-friendly replacement parts. For a daily-driven Jimmy, GMB U-joints offer a good balance of quality and cost.
How Much Does a U-Joint Replacement Cost for a 1982-1995 GMC Jimmy?

Frequently Asked Questions
How many U-joints does my GMC Jimmy have?
It varies. A 2WD model typically has two U-joints on the rear driveshaft. A 4WD model has those two, plus additional U-joints on the front driveshaft. Some configurations may even have a third joint on a two-piece rear driveshaft. The best way to know is to visually inspect your vehicle.
What happens if a U-joint fails completely?
Complete failure is serious. The driveshaft can detach from the vehicle, causing you to lose all power to the wheels. If this happens at speed, the loose driveshaft can flail around, causing catastrophic damage to your transmission, exhaust, and undercarriage, and could lead to a loss of vehicle control.
Can I replace a U-joint myself?
Yes, if you have the right tools and are comfortable working under your vehicle. The job requires removing the driveshaft and using a press or a combination of sockets and a hammer to force the old joint out 🎬 Watch: The easy way to change universal joints and the new one in. It can be difficult if the parts are rusted. Always mark the driveshaft's orientation before removal to avoid re-installing it out of balance.
🎬 See this S-10 U-joint replacement using hand toolsShould I replace all the U-joints at once?
It's not always necessary, but it can be a good idea. If one U-joint has failed due to age and mileage, the others are likely not far behind. Since the driveshaft must be removed to replace one, replacing all of them at the same time can save you from doing the same job again in the near future.
